How to fix?

This issue was patched in RHSA-2023:4707.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python3-subscription-manager-rhsm package and not the python3-subscription-manager-rhsm package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

A vulnerability was found in subscription-manager that allows local privilege escalation due to inadequate authorization. The D-Bus interface com.redhat.RHSM1 exposes a significant number of methods to all users that could change the state of the registration. By using the com.redhat.RHSM1.Config.SetAll() method, a low-privileged local user could tamper with the state of the registration, by unregistering the system or by changing the current entitlements. This flaw allows an attacker to set arbitrary configuration directives for /etc/rhsm/rhsm.conf, which can be abused to cause a local privilege escalation to an unconfined root.
